EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 504,332, datedSeptember 5, 1893.

Application filed April 19, 1893. Serial No. 470.985. (No model.)

.To all whom it may concern:

,Be it known that We, EMILE CORNELY and ROBERT CORNELY, residents ofParis, France, have invented a new and useful Improvement inEmbroidering-Machines, which is fully set forth' in the followingspecification.

The present invention relates to lnachines for embroidering stockings,gloves and similar articles for which purpose the machine is providedwith a cylindrical or other shaped narrow arm or bed-plate on which thehollow articles to be embroidered can be placed.

Our invention can be fully understood in connect-ion with theaccompanying drawings constituting part of this specification, in which-Figure i, represents a vertical section (full size) through the improvedarm and mechanisrn for producing the stitch. Fig. 2, represents ahorizontal sectional view of the same; Fig. 3, a vertical section (fullsize) of a portion of the arm as it has been constructed heretofore, andFig. 4 is an enlarged vertical section of the looper-pinion.

The size of the arm as employed heretofore and represented in Fig. 3could not be reduced in its dimensions for the reason that the stitchproducing parts of the machine composed of the screw rack A, theoscillating screw pinion B and its looper C which operate in conjunctionwith the needle hookD had to be lodged within said arm of the machine,and therefore neither its thickness a h nor its length cd could be inany wise reduced which made itimpossible to embroider gloves andchildrens stockings. In order to obtain therefore, an arm of muchreduced size the screw rack A and its screw pinion B have been disposedto the rear of the arm N of the machine. The pitman E (receiving itsmotion from the main shaft of the machine) drives, in the well knownmanner, thelever F, which imparts a reciprocating motion to the rod G ofthe screw rack A, and an oscillating motion to the screw pinion B; butthe latter instead of being provided with the looper C as heretofore andas represented in Fig. 3, is provided with a pinion H which communicatesits motion to pinion I, shaft K (which passes through a hollow portionof the arm) and pinions L and M, which latter acts as looper, it beingprovided with proper openings for the passage of the'thread, asrepresented on an enlarged scale in Fig. 4. As the pinion I, shaft K andpinionsL and Mcan be brought within a very small compass, it followsthat the size of the arm N can be vmuch reduced, not only in height andwidth, but also in the length of its projection beyond the needle-hole,as shown in Fig. 1 in full size by the distance c d. The operating partsherein described as well as the needle and the feed are directed bymeans of the crank-handle O, and pinions P, Q, R, S, T and U in asimilar manner as heretofore but with slight changes in theirdisposition, such as were required by the new disposition of the screwgearings A and B. The arm N is provided with a groove 0c (Fig. 3) inwhich the thread lies in passing from the bobbin to the looper.

I-Iaving thus described our invention, what we claim is- Y In a machinefor embroidering gloves, stockings and similar articles the combinationwith the crank-handle of the universal feed mechanism of a hollow armconstitutingthe bed-plate for the work, a looper-pinion supported in abearing at the inner end of said arm, a shaft extending through thelatter and having a pinion engaging with the looper pinion, ascrew-pinion geared to the outer end of said shaft, a reciprocatingscrew rod engaging said-screw-pinion, said rod and pinion being bothlocated outside of said arm, means for reciprocating said pinion andconnections for rotating the looper driving mechanism upon the movementof the crank-handle, substantially as described.

In testimony whereof we have signed this speeication in the presence oftwo subscribing witnesses. l
